Description Dominik Kummer 2025-03-08 22:25:26 UTC

The display priority settings in display configuration does not correlate to `randr --listmonitors` indices. Is that intentional?
I just experienced a situation where the second of three screens had to be disconnected temporarly. After reconnecting it, its index became 3. This wrong order persisted across reboot.
To restore the original indexing I had to connect primary and second screen. Then reboot. Afterwards I had to connect the 3rd screen, and reboot again. Now the original order was restored.
